Plus, if you think table-nesting is too complex/difficult to implement, combining div, table, and float would allow for pesudo-table-nesting.

#2 - tbl or table with widthBecause the current BBCode doesn't allow table-nesting, tables are almost useless for styling content. They're basically reduced to being tightly-crammed grids. Allowing the use of a width modifier/style would give us a simple means of displaying our content in a more appealing way. Height would be nice, too, but width is more important for layouts - especially for signatures.

Though, if you gave us div with a width property and nesting ability, those of us who really care about styling would be able to stack divs into what would be completely customizable table cells.

(2) Signature character limit

It's fine for people who use images or limited text, but adding descriptive text and BBCode is very difficult with the limit so low - and that's without even considering an attempt to create centered columns.

If you gave me just div, table, and an increased signature character limit - without width or height or nesting properties - I'd be able to make some cool-looking, but simple, stuff.
